stock is progressive so it depends on how depressed the spring already is (initial rate is very low, and it increases). That said, somewhere around 200-250 probably, maybe twice that in the rear. I had 580F/650R and was looking to go stiffer (giggity)

swift makes nice but expensive springs. I can never remember for sure but I'm pretty sure the spring itself counts as "sprung" weight so the lighter spring is kinda negligible. IDK what lengths you E8/9x $#@!ers run but I remember they didn't have much in my size

there's this one beer I had in slovakia called Kelt that I liked, still haven't found it in any store here that carries eurosnob beer. That and wyborowa vodka from poland which you'd think would be here.

again...i'm going from fuzzy memory here so I could be wrong, but GC is basically a koni/eibach setup (completely proprietary to GC). Konis take abuse well, and springs are springs. But for the price I don't know that doing it all over, I wouldn't have gone with a GC setup over my ASTs

Introduction:

The 5000 Series damper stands as AST's full race setup. It is available in one, two and three way adjustments. 5000 Series coilovers are fully streetable but utilize the full race components like inverted struts, teflon flat bearings and spherical bearing mounts. 5000 Series coilovers are great for competitors with points based rules or rule-free damper requirements. The 5100 gives the customer the ability to have the highest end components without running reservoirs. 5200 models use remote reservoirs or "piggyback" reservoirs to control low speed compression. 5300 models use remote reservoirs or "piggyback" reservoirs to control low and high speed compression.

Key Features:

Monotube shocks and struts that use 44.5mm shafts for struts and 14mm shafts for shocks
Nitrogen charged to 265 psi for all models
Utilizes AST's Load Bearing Piston (LBP) for all strut designs (AST is the only coilover in this price range to use this feature)
Steel bodied struts use European KTL coating which is stronger and more weather resistant than powder coat or wet paint found on most shocks
All shock models use high grade aircraft aluminum for bodies
All shock models (where applicable) use spherical bearing mounting points. Pin style spherical top mounts are available for purchase separately
Available as Rebound-only adjustable (5100) or Rebound/Compression adjustable (5200), Rebound/Low Speed Compression/High Speed Compression (5300)
Fully rebuildable and revalvable
Shortened appropriately for lowered race cars
All kits include hardware for installation
The 5000 series have been tested at events including the 24 Hours of Nurburgring, SCCA Nationals, NASA Nationals, 25 Hours of Thunderhill and Grand Am races
Wins in Redline Time Attack, SCCA Nationals, and NASA Nationals
Valved for an agressive street ride that performs great at the track

Modularity:

One key feature on the 5000 series shocks is modularity, which makes them easily upgradeable. This provides an upgrade path for customers on a tight budget that want an adjustable, high performance, race-ready shock but can't quite afford the double adjustable 5200 or triple adjustable 5300. Simply purchase 5100s, and when you're ready, send your ASTs to an authorized rebuild center to upgrade them to 5200s or 5300s with remote reservoirs. Rest easy knowing that your shock absorber investment will perform today and in the future, as your budget and needs grow.

Retail is $3090

Asking $2781

Kit includes front struts, rear dampers and 1M/M3 adapter sleeves. Springs and camber plates are extra and will add $1100 to the price of the dampers.

Not a fan of eibach or koni however. Then again i really don't know my elbow from my $#@! when it comes to suspension apparently.
